Pollution is an issue which potentially affects all of humanity. Due to the fact that it takes a large variety of forms, there are very few persons around the world who do not experience some form of pollution in one way or another. The major forms of pollution are land pollution, air pollution and water pollution. Since the 20th century, excessive noise has increased to such a level that it is now considered another form of pollution. The rise in pollution and pollutants can be considered to be linked to two factors: The rapid expansion in the human population over the last few centuries as well as the spread of industrialization around the world. Waste products from the various industrial processes, particularly from those involving fossil fuels, can have devastating effects on various ecosystems if they are not properly dealt with.
